• Console Metrics — %Monitor.System.Sample.Dashboard Monitors the cconsole.log file.Alerts may be defined on severity level. The System Monitor always monitors thecconsole.log file, and provides alerts for severity level of Severe or higher.These classes monitor counters of system activity. You can obtain global metrics for all theglobals in the current namespace (%Monitor.System.Globals) and system metrics for totalsystem activity (%Monitor.System.SystemMetrics). You can also obtain global and systemmetrics relative to:• Routines — %Monitor.System.Sample.Routines) – for each routine currently executing• Processes (%Monitor.System.Sample.Processes)– for each Caché processAlerts2.5 AlertsAn alert specifies a list of properties in a class to monitor. An expression is specified, forexample, “%1 < 100 && %1 > 20” . During Monitor sampling, the values of the propertiesin the class are evaluated. If the expression evaluates to true, an alert is triggered. A notificationaction is taken whenever an alert is triggered.The expression provides for parameter substitution. %1 indicates the first property in the listof monitored properties, %2 the second property, etc.An Alert is defined by using the Monitor Manager Alert management functions.2.6 Managing the Application MonitorThe Monitor Manager (^%MONAPPMGR) is a character-based utility that allows the userto do Management functions. It may be executed in a user’s namespace, and sets parametersfor that namespace only. In this way, multiple Managers, each with their own activated classes,and notification options, may all run at the same time.Caché Monitoring Guide 17
